We all broke the casing of the 18650, 20700 or 21700 battery.
Some still use it that way, which is dangerous. Others fix it with tape or just throw it away.
Well, now you can save all the unsafe batteries that have envelopes compromised with wrappers.
Each package contains:
4 18650, 20700 or 21700 Wraps in the design of your choice
It is highly recommended that you use a hair dryer when applying the new wrapper.
The old wrapper must be removed first!
Also, do not lose the top plastic ring of the battery, as it comes out with the old housing.
Damaged batteries can be dangerous, notches and tears in the sleeves can cause direct short circuits to cause battery ventilation and even fires.
This solution is not only cheap, but also effective and very easy to apply.
